Which of the following is a common garnish for grilled steaks at Cooper's Hawk?

Fresh herbs are commonly used as a garnish for grilled steaks at Cooper's Hawk. They enhance the dish's flavor profile and add a touch of color and freshness that elevates the presentation. Fresh herbs, such as parsley, thyme, or rosemary, complement the savory notes of grilled meats while adding an aromatic quality that enhances the overall dining experience.

In contrast, options like sour cream might be more suited for specific dishes like baked potatoes or certain sauces, but are not a traditional or common garnish for steak. Olive oil, while a delicious addition to various preparations, typically serves more as a cooking medium or finishing oil rather than a garnish. Butter can also be used in cooking or as a finishing touch for steak, but it's not as prevalent as fresh herbs in providing a vibrant and fresh element to the dish.
